Scientists Captured Rare Video of Deepstaria, a Bizarre Jellyfish That Changes Shape

Even among all of the strange and mysterious group of ancient animals known as the jellyfish, the Deepstaria jellyfish is unique. A fact that has now been recorded on video by the Nautilus, a Pacific Ocean research vessel.

Fun fact: the Nautilus has also captured footage of a googly-eyed stubby squid and a weird purple orb.

Live Science reports that, halfway between the U.S. and Australia, the Nautilus spotted a jellyfish that appeared as a ghost….at first.

#Repost from @mbari_news with @regram.app … The scyphomedusa Deepstaria is certainly odd, with its bag-like appearance, and bell that can open more than a meter wide. Speculation on the identity of a mystery blob has become a sensation online, sparking heated and entertaining debates over its identity. We've seen this unusual jellyfish with MBARI's ROVs around 30 times in 30 years from depths of a few hundred meters to about 2,000 meters deep! Surprisingly, according to morphological and genetic studies, its closest relative is one of the most commonly observed jellies in our area — the moon jelly, Aurelia aurita.⠀ ⠀ #deepstaria #jellyfish #jellies #pelagic #midwater #ROV #scyphomedusa⠀ #deepsealife #deepsea #ocean #oceanlife #sealife #plankton #mesopelagic #MBARI #underwaterphotography #marinebiology

Then, it unfurled and they got a glimpse of the geometric mesh membrane that revealed its identity: Deepstaria. That, along with its distinctively flowing bell and lack of tentacles, are its most distinguishing features.

The rest of the video is the jellyfish changing shape, from what looks like a crumpled plastic bag to a blanket.

The jellyfish was first discovered by a submersible called the Deepstar 4000 (designed by Jacques Cousteau) in the 1960s, and since then it has only been spotted about a dozen times. Most of the details of its existence remain a mystery to researchers.

Deepstaria enigmatica. This jellyfish was named after the research submersible Deepstar 4000, which collected the first specimens of this genus in 1966. This species is the home to another species, namely an isopod called Anuropus, which can be seen through the mantle of the jellyfish (on the upper right side of the bell). These animals probably form a symbiotic relationship, perhaps eating food captured by the jellyfish. ⠀ ⠀ Watch a video about this unusual jelly on MBARI's YouTube channel: http://ow.ly/JTf6u⠀ ⠀ #jellyfish #stragethings #deepstaria #MysteriesoftheDeep #MBARI #expedition #midwater #MontereyBay #deepsea #deepsealife #ROV #MarineTechnology #Technology #Robot #MarineBiology #Ocean #oceanlife #oceanscience #sealife #underwaterphotography #Nature #wildlife⠀⠀

That’s not likely to change anytime soon, which makes this video all the more spectacular.

Science is so cool, y’all. Images like these make it pretty darn hard to disagree.

Scuba Divers Captured a Photo of a Human-Sized Jellyfish

Only people brave enough to spend time without immediate access to unlimited oxygen get to see the crazy creatures that lurk under the surface of the sea.

Luckily for the rest of us, some of those people go into the deep armed with cameras – which is exactly how Dan Abbott and Lizzie Daly dove into the Celtic Sea the day they ran across a giant barrel jellyfish (Rhizostoma pulmo). How giant?

It was the size of person.

The giant barrel jellyfish is not the largest species of jellyfish in the world (that title belongs to the lion’s mane jellyfish, which can grow up to 120 feet from top to the end of the tentacles – about the length of a blue whale), but it is the largest species anyone could expect to run into off the Cornish coast.

While the lion’s mane jellyfish has a sting full of neurotoxins, the giant barrel jellyfish’s translucent, frilly tentacles are mostly harmless (aside from a minor sting).

The one captured on film by Abbott, an underwater cinematographer, was about 3 feet wide and 6 feet long.

Day 7 WILD OCEAN WEEK 💙 | GIANT Barrel Jellyfish

Diving with a giant barrel jellyfish in Cornwall to celebrate the end of #WildOceanWeek 💙Massive throw to Sharkman Dan for the wonderful footage Spend 2 minutes of the end of WILD OCEAN WEEK watching this beautiful moment where I come face to face with a barrel jellyfish THE SAME SIZE AS ME while diving off of the coast of Falmouth 💙So excited that I actually say 'Barrel Fish' instead of Barrel Jellyfish ha!!!What an INCREDIBLE experience – both Dan and I have never seen anything like it. I couldn't think of a better way to finish the week in celebrating our incredible oceans.For anybody who is in Cornwall do come on down to Maenporth tomorrow at 12pm for a beach clean. There should be a good crowd of us rounded up now so it will be fun – and it will be followed by a small talk about the trip! See you THEN xMarine Conservation Society Cornish Diving CentreThe Wildlife Trusts @Cornwall Wildlife Trust Falmouth Cornwall UK

“What an INCREDIBLE experience.” wrote Daly in a Facebook post. “Both Dan and I have never seen anything like it. I couldn’t think of a better way to finish the week in celebrating our incredible oceans.”

If you’re hoping to have a similar experience, you’ll probably have to take up diving or snorkeling out at sea. These jellies rarely wander close to the coast, though they occasionally will, if lured by a large plankton bloom like the UK saw in 2002, 2014, and 2019.

Make sure and check out the full Wild Ocean Week video if this sort of thing intrigues you – under the sea is definitely one of the last great frontiers!

A hydra, a freshwater cousin…

A hydra, a freshwater cousin of the jellyfish, can survive being chopped in a blender. Its pieces will crawl their way back toward each other to reassemble as a complete organism. 00
